The Edelstein magnetization represents an explicitly time-reversal symmetry breaking perturbation, that, in turn, can have a non-trivial detrimental back action on the superconductor itself. A reduction of the critical current can result from the induced dipolar fields, especially when the size of the induced moment locally overcomes the critical magnetic fields. The supercurrent can thus be an optimal indicator in systems where an applied electric field varies the intensity of the Rashba coupling. We argue that the orbital Edelstein effect could have a non-trivial role in the suppression of critical current recently reported in experiments where an electric field is applied to metallic superconductors [1]}.
